Just as a humorous aside, in Ye Olden Days, when no one but a prostitute knew the going rate for a condom, the ice cream trucks only rang a bell.

But the tunes bring "attention-getting" to another plane. "Jingle Bells" in July? That's when you know the person who picked the songs needs a bit more instruction in American culture or they work for a large retailer.

Tell that to the ice cream truck that idles with the song playing half a block away for twelve hours every saturday...
